The OASys is a highly efficient, environmentally benign, and low maintenance cooling system.  because 

of the unique nature of the OASys compared to conventional refrigerant air conditioners, a thorough 

reading of this manual is highly recommended to assure that you benefit from its comfort and energy 

advantages.

“OASys” stands for Outdoor Air System.  Instead of re-circulating indoor air OASys delivers 100% out-

door air, filtered through a water saturated media.  And instead of compressing a gas to achieve cool-

ing, the OASys provides cooling by evaporating water using a unique two-stage process.  The following 

features show why the OASys is an entirely new class of air conditioner:

• 80% reduction in energy consumption (EER 40+)

•  Two stage cooling results in lower air temperature, less humidity than single stage evaporative 

coolers, and superior comfort

• Variable speed operation is provided by a three speed motor.

•  Single blower and dual pump design means fewer moving parts, less maintenance, and lower 

operating cost.

•  Intelligent controls enable the unit to precisely maintain water quality, reducing maintenance and 

conserving water.

• Easy access to all components simplifies maintenance and repairs.

Sys, read the Operations section.  To learn the principals of operation, refer to the sections General use
